Changelog » Change #4488

• adds an "anchor" to the bottom of the messages elements

  • adjusts message element management to ignore the anchor element

• adds ScrollManager

  • central class for deciding when to scroll to bottom
  • during scrollMode = smart, automatically decides when to enable/disable autoscroll
  • 50px threshold for automatically enabling and disabling autoscroll

• replaces all scrolling behavior with scrollManager.scrollToBottom()

  a bit different from existing behavior, but i think this is ultimately the right behavior and simpler in the long run
